Abstract
The invention provides a fatty acid polyoxyethylene succinate. The fatty acid polyoxyethylene succinate is is characterized by having a structure as shown in the specification, wherein n is an integer between 2-15; R is an alkyl with 7-19 carbon atoms. The fatty acid polyoxyethylene succinate has good lubricity, is dissolvable in water to be prepared a water soluble cutting solution, has excellent cooling performance and good biodegradability, simultaneously is a good surfactant, and can be used in other lubricants using oil as the main component to prepare an emulsion liquid.
Description
Technical field
The present invention relates to synthesising chemical technology field, specifically aliphatic acid polyethenoxy succinate and preparation method thereof and prepare micro cutting liquid with this ester.
Background technology
The lubricant usage quantitys such as the machining oil of conventional metals processing and lubrication and cooling use, refrigerant, emulsion are large, and traditional machining oil is all that employing mineral oil is base oil, in physical environment, be difficult for decomposing, additive used is mostly harmful to human body and environment, not only waste resource, also can cause the huge pollution of processing site and environment.In recent years the research of micro cutting technology is obtained to very large progress, reduced the harm that the discharge of a large amount of cutting fluid causes environment, but the workpiece processing to clean and just can enter next procedure toward contact, need to use a large amount of clean-out systems.
As the publication number Chinese patent that is CN101376863, disclose a kind of micro quantity lubrication system aluminum alloy cutting fluid and its production and use, adopted weight percent raw material to be prepared from: base oil 30%, sulfide isobutene 5~20%, clorafin 5~20%, thiophosphatephosphorothioate 5~20%, potassium borate 5~20%, tensio-active agent 10%, rust-preventive agent 5%.Although this cutting fluid has good lubrication performance, but the workpiece processing will clean and just can enter next procedure toward contact, need to use a large amount of clean-out systems, can bring larger pressure to environment.
Summary of the invention
In view of above defect, the object of the invention is to overcome the deficiencies in the prior art, in the production that provides a kind of some surface active property aliphatic acid polyethenoxy succinate that workpiece clear water good, that process just can easily clean and be applied to lubricant, obtain a kind of water-soluble micro cutting liquid of lubrication and cooling excellent performance.The workpiece simultaneously processing only uses clear water just can clean up entering before next procedure, easy and simple to handle, environmental protection, low-carbon (LC).
For achieving the above object, the invention provides a kind of aliphatic acid polyethenoxy succinate, it is characterized in that thering is following structure:
Wherein, the integer that n is 2~15;
R is alkyl, is preferably carbonatoms and is alkane or the alkene of 7~19.
In addition, the present invention also provides the preparation method of above-mentioned aliphatic acid polyethenoxy succinate, it is characterized in that: generated after aliphatic acid polyethenoxy ether by lipid acid and oxyethane polymerization reaction take place, then react generation aliphatic acid polyethenoxy succinate with succsinic acid.
Above-mentioned concrete reaction equation is:
Wherein, the integer that n is 2~15;
R is alkyl, is preferably carbonatoms and is alkane or the alkene of 7~19.
In addition, the present invention also provides above-mentioned aliphatic acid polyethenoxy succinate preparation method's concrete technology step:
Step 1, lipid acid is dropped in polymeric kettle, add after initiator, stir.
